The document discusses the concept of positive and negative values in various real-world contexts, such as speed limits, weight, golf scores, stock market indices, and electricity generation. It provides examples of how these values relate to performance, measurements, and outcomes, illustrating their significance in everyday life. The text concludes by encouraging a positive attitude towards learning about integers in mathematics.
Integers in the Real World
- 2. We can drive OVER the speed limit (+15km/hr) or UNDER the speed limit (-10km/hr). Both of these can cause traffic problems.
- 3. • We can be OVERWEIGHT (+ 10kg), or we might have an eating disorder and be UNDERWEIGHT (-25kg).
- 4. • Each golf hole has a “Par” or amount of shots it should take to get the ball in. • UNDER PAR is negative and Good • OVER PAR is positive, (meaning it took you more shots than “par” and is not so good). (Continued next Slide)
- 5. Integers and Golf • Here are some innovative ideas to make it easier to achieve “Par” on the Golf Course.
- 6. Each week a given Song can move UP the charts gaining places (Positive), OR drop DOWN in the charts falling places (Negative).
- 7. There are indexes for the markets to indicate how shares have gone that day. (All Ordinaries, The Dow Jones, The Nikei). Index can go UP (positive), or DOWN (negative).
- 8. Positive and Negative charges from atoms make Batteries generate electricity for us.
- 9. Positive and Negative charges from atoms are also used for electroplating silver onto spoons and jewellery.
- 10. Downloading data onto our computer ADDS data to our disc (positive), while Upload sharing to others sends data out (negative).
- 11. Thrust power (positive) pushes a rocket upwards against earth’s gravitational force (negative).
- 12. Floors above ground level are positive, while the underground car park levels are negative. Burj Kalifa - World’s tallest building. Level 124 = observation lounge, total height 160 stories. Visited by Passy’s World in 2010 – Awesome
- 13. Pyramids -2500 BC Burj Kalifa +2010 AD
- 14. The positive force of a drag racing car at full speed is far too big to be overcome by normal braking. It is like an integer sum of 1000 and -300. There is still 700 of forward force to cancel out before the car can reach zero and stop moving.
- 15. To create enough Negative braking force for the drag racer to stop, parachutes are needed as well as huge powerful disc brakes. Negative Braking Force Positive Force
- 16. When a plane takes of it is ASCENDING above ground level (Positive), and when it comes in to land it is DESCENDING (Negative).
- 17. Brakes supply a Negative direction pull against the forward motion of the truck and its load. The trailer brakes need to re-adjust to balance each trailer load against the truck’s brakes. Forward Motion of Truck Trailer Brakes Truck Brakes
- 18. If the truck brakes too hard compared to the trailer, then we get the classic jack-knife type truck accident occurring.
- 19. For an initial $20 invested on a Gaming Machine, you might be $5 up (Positive), or more likely down $15 and losing (Negative).
- 20. You can be racing at under world record time, (Negative), or be outside of the world record time (Positive).
- 21. Mt Everest 8.8km above sea level (Positive) and the Mariana Trench is 10.9km below (Negative).
- 22. At the summit of Mt Everest, the Oxygen availability is below (Negative) the required level for human survival.
- 23. Getting Paid and Savings are Positive, Loans and Debts are Negative money amounts.
- 24. • Increases are Positive, and Decreases Negative.
- 25. Drug Tests can be Positive, meaning you do have the drug in your system, or Negative.
- 26. Integers and Blood Pressure Your Blood Pressure might be too high (Positive), but it can also be too low (Negative).
- 27. Feeling Positive ? Hopefully learning a bit more about Integers in the real world will make you feel even more POSITIVE about Mathematics.
